Keiser Biaxial Upper Back – Used

Specifically designed to isolate the upper back, the A350 Biaxial Upper Back differs from anything else. It guides you through a range of motion that optimizes the effect on all of the muscles of the upper back. It’s unilateral movement promotes symmetry by preventing the strong side from helping the weaker side. Unlike conventional machines that use iron, the A350 Biaxial Upper Back’s low‑inertia design gives you a smooth resistance. And it’s perfect for people at any fitness level. 

Features you won’t find in conventional machines

• Unique axis of rotation allows greater range of motion in natural planes of movement

• Unilateral movement means each limb can be trained symmetrically

• Large digital display that shows resistance, sets, repetitions, and peak power

• Thumb buttons let you change resistance without changing position — even during exercise

• Fast, easy, and precise eccentric overloading

• Change resistance in increments as small as one pound

• Industry-leading lifespan and uptime for years of use

• Unique versatility; five ways to train instead of only one

• Fully adjustable to accommodate a wide range of users

Control resistance with digital convenience and precision

THUMB BUTTON CONTROLS

Thumb button controls on handgrips let you change resistance without changing position.

Change resistance during exercise without stopping.

Convenient resistance controls are perfect for quick, precise, eccentric overloading.

POWER DISPLAY

Get instant feedback for testing and evaluation. The Power Display shows:

• Resistance level in (lbs. or kg)
• Sets
• Repetitions
• Peak power produced on each repetition
• Percentage of peak power
• Adjustment positions

Six-repetition Peak Power test calculates the resistance at which you achieve maximum power. Clear, one-inch numbers can be seen from a distance.
